This comment be updated to call out the new TSX_CTRL behavior.

/*      * On TAA affected systems:      *      - nothing to do if TSX is disabled on the host.      *      - we emulate TSX_CTRL if present on the host.      *      This lets the guest use VERW to clear CPU buffers.      */

Ok.

Hmm, but the comment is even more accurate now than before, isn't it? It said nothing about hiding TSX_CTRL, so now it matches the code below.
